Anything is a bubble with a long enough (or short enough time scale)

Housing was a bubble in 2008. Bitcoin was a bubble in 2013, 2017, and 2021. What matters is do you believe in the long term thesis.

I happen to currently believe in the long term thesis of housing (in my jurisdiction) and bitcoin (and many other things) when measured against fiat. Bitcoin might disrupt those other things, but it is the measuring stick for now… poor one though it may be.
